In our opinion: ◆ the pro forma financial information has been properly compiled on the basis stated; and ◆ that basis is consistent with the accounting policies of the issuer. This report has been issued solely for the purposes of: ◆ filing the registration document with the French financial markets authority (Autorité des marchés financiers – AMF); ◆ And, as the case may be, the admission to trading on a regulated market, and/or a public offer, of shares or debt securities of Aéroports de Paris in France and in other EU member states in which the prospectus approved by the AMF is notified. and cannot be used for any other purpose.
